This is newly installed server. I don't know where the error is: on the Zimbra desktop side or on the server side?

How do I diagnose this?

I've dis-installed V1.4 and installed Beta 2 on my Windows 7 Ultimate and it work now.

Something weird happened:
- I installed
- I started Zimbra Desktop
- I got a message "Initiallizing" with an Ok button,
- I got the dots rotating
it stalled there for 20-30 minutes (I let it run for a while to make sure it was really stalled.
- I stopped with the X button top right
- I restarted ZD again
It worked...

So it's a try and try again thing in my case.

It's really good when it works... makes you want to have it everywhere...

When the programming things makes it stable and idiot proof, this is going to be an Exchange killer...

But, without stability, however cool this application and server is....
